Define a host

Using ThinkSystem System Manager, you define the hosts that send data to the storage array. Defining a host is one of the steps required to let the storage array know which hosts are attached to it and to allow I/O access to the volumes.

1. Select Storage > Hosts.
2. Click Create > Host.
   The Create Host dialog box appears.
3. Select the settings for the host as appropriate.

   Field details

   Setting	Description
   Name	Type a name for the new host.
   Host operating system type	Select one of the following options from the drop-down list: ThinkSystem 11.60 and newer Linux Pre ThinkSystem 11.60 Linux DM-MP (Kernel 3.10 or later)
   Host interface type	Select the host interface type that you want to use. If the array you configure only has one available host interface type, this setting may not be available to select.
   Host ports	Do one of the following: Select I/O Interface If the host ports have logged in, you can select host port identifiers from the list. This is the recommended method. Manual add If the host ports have not logged in, look at /etc/nvme/hostnqn on the host to find the hostnqn identifiers and associate them with the host definition. You can manually enter the host port identifiers or copy/paste them from the /etc/nvme/hostnqn file (one at a time) into the Host ports field. You must add one host port identifier at a time to associate it with the host, but you can continue to select as many identifiers that are associated with the host. Each identifier is displayed in the Host ports field. If necessary, you also can remove an identifier by selecting the X next to it.
